METHOD OF AND DEVICE FOR MAKING WOODEN LASTS.

SPECIFICATION forming part of Letters Patent No. 355,615, dated January 4, 1887;

I] Application filed Sepember 27, 1853: Serial No. 107,545. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM KINGSTON, a

citizen of the United States, residing atLittle.

Falls, in the county of Herkimer and State of New York, have invented. certain new and useful Improvements in Methods of and Devices for Making Wooden Lasts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to let ters or figures of reference marked thereon, which form a part of this specification.

The object of the present invention is to obviate the necessity of finishing the toe and heel portions of wooden lasts byaskilled workman or a machine specially devised for the purpose. I

l/voo'den lasts as heretofore made in a lathe always possessed front and rear projections, by reason of the centering-dogs being applied to the centers of the curved toe and heelsurfaoes. These projections are in the method devised by me brought to other points than the curved toe and heel surfaces, and can readily be removed by an unskilled workman. In other words, it is the aim of my invention to turn a wooden last which shall have perfectly true toe and heel surfaces, and Iaccomplish this in the manner hereinafter described and claimed.

In the drawings, Figure 1 is a side view of the model or pattern used in carrying out my method. Fig. 2 is a side view of the last as turned in the lathe and having projections at the top and bottom. Fig. 3 is a view showing the old form of last with end projections.

The model or pattern A (shown in Fig. 1) has plates a, screwed or otherwise secured to itstop and bottom surfaces. These plates project beyond the ends of the model and engage with the centering dogs or chucks b of alathe. If desired, these plates or devices for holding the model between the lathe-centers can be dispensed with, and the centers may be in the form of gripping devices, which reach onto and under the last-pattern and hold the same.

Instead of applying the plates a to the bottom and top of the pattern, they can be secured to the sides of the same. In every instance,however, the last-pattern is caught or held at other points than the ends. It will thus be manifest that the last B turned'orinade in the lathe has the end projections, 12, located at other points than on the curved toe and heel surfaces, and consequently I am enabled by my method to turn or make a wooden last which on the curved toe and heel surfaces. The projections .b can easily and quickly be out off by an unskilled workman, whereas the projections or lumps cleft on the ordinary last,O, as seen iii-Fig. 8, require the work of an experienced work man to remove them and properly shape or finish the ends of thelast.

lhe advantages of my method over the existing one of making wooden lasts are obvious, and I may only state that I materially lessen the cost of manufacture of wooden lasts by turning-them in a lathe with true or properly curved toe and heel portions.

It will be perceived that this improvement need not necessarily be used for both the toe and heel of a last. If only one end of the pattern-last is centered according to my inventionthe toe, for eXampleand the other end centered in the old way, then the toe will be turned on the lathe and the heel will have a stub.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

l. The method herein described of turning wooden lasts with curved and finished toe-surfaces, which consists in holding or centering the forward end of the pattern-last at a point below the toe, whereby the lathe or turningtool finishes the toe and leaves the frontstub of the last-blank projecting from the sole of the last below the toe,and afterward removing the said stub, substantially as herein set forth.

2. The method herein described of turningwooden lasts with curved and finished heelsurfaces, which consists in holding or centering therear end of the pattern-last at a point above the heel, whereby the lathe or turningtool finishes the heel and leaves the rear stub of the last-blank projecting from the surface- 'does not require the final finishing operation I A tering the pattern-last at points above the heel afterward removing the said stubs, as herein of the last above the heel, and afterward re moving the said stub, substantially as herein set forth.

3. The method herein described of turning wooden lasts with curved and finished toe and heel surfaces, which consists in holding or conand below the toe, whereby the lathe or turning-tool forms the stubs or projections of the last-blank on the substantially-flat surfaces of the last above the heel and below the toe,and

set forth.

4. In the manufacture of wooden lasts, alast pattern or model provided with means for centering the toe of the pattern in a last-turning lathe at a point below the same, substantially as and for the purpose herein set forth.

5. In the manufacture of wooden lasts,a last pattern or model provided with means for centering the heel of the pattern in alast-tur-ning lathe at a point above the same, substantially as and for the purpose set forth.

6. In the manufacture of wooden lasts,alast pattern or model provided with means for centering it obliquely in a 1ast-tnrning lathe at points above the heel and below the toe, substantially as and for the purpose herein set forth. I

7. A last pattern or model having plates or centering devices a, attached at other points than the ends thereof and extending beyond said ends, as herein set forth.

In testimony whereof I affix my signature in presence of two witnesses.
